Low profile deadbolts: modifications and suggestions.

A low profile lock is one that measures less than ¾” from the plane of the key entry to the surface of the door.


Low profile locks don’t have enough depth to fit Level Bolt without causing the motor to bind. So, if you have a low profile lock, you’ll need to make some adjustments.

(You can watch this Low Profile Modifications video to learn more.)

To figure out whether you have a low profile lock:

  1. Measure the distance between the surface of your door and the key entry.
    This is the profile of your lock.
  2. If the measurement is less than 3/4” (19mm), you have a low profile lock.

Some manufacturers of low profile locks (Baldwin, Emtek, etc.) offer extra hardware, either in the box or upon request, that increases the depth of the exterior housing, making the lockset compatible with Level Bolt. The hardware pieces go by a few different names:

  • Cylinder collar spacer
  • Cylinder extension ring/spacer
  • Trim extension ring/spacer

If you have a low profile lock, you can search the Internet for “thin door kits”, or contact Support to get help.

If your existing deadbolt is not tied in with your design aesthetic, you may consider replacing it with Level Lock+Level Lock – Touch Edition, or Level Lock.
